Abstract

Uranium(VI) is one of the most harmful and carcinogenic ion if present in water above its permissible limit. The main objective of this study is removal of uranium(VI) from water sample using nano zerovalent iron prepared by green synthesis approach with the help of Annacardium occidentale testa extract in which the whole process is completely environmental friendly and cost effective and does not involve any hazardous chemicals. Size of AO-Fe nanoparticle is characterized through UV-visible spectroscopy and FTIR analysis. Morphology of nanoparticle is studied using SEM-EDS and XRD analysis. The adsorption capacity of AO-Fe nanoparticle is studied using batch experiments. Effect of different parameters are then analyzed such as pH, adsorbent dosage, contact time and U(VI) ion concentration. Adsorption isotherm is also studied using Langmuir and Freundlich adsorption isotherm where correlation constant R2 is about 0.99.
